DailyDirt: Long-Lasting Concrete Ideas

from the urls-we-dig-up dept

Every year, people pour billions of tons of concrete to build the stuff we live in and drive on. Concrete is everywhere, so it'd be nice to find better ways to make it and to make it more durable and to last longer. (FYI: Concrete is usually made up of 10-15% cement, and the cement is used to bind together sand and/or crushed rocks in concrete.) Here are just a few links on making better concrete. If you'd like to read more awesome and interesting stuff, check out this unrelated (but not entirely random!) Techdirt post via StumbleUpon.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

–The Techdirt Team

    Superhydrophobic concrete would very likely make a horrible material for roadways, because hydrophobic materials tend to have one other thing in common: low friction. Which doesn't sound so bad until you realize that in the context of vehicles and roads, friction is more commonly known as traction, and surfaces that don't have much of it are called "slippery" in layman's terms.
